feat: Enhance Nostr chat functionality with improved authentication and error handling

- Integrate authentication token retrieval for loading peers and current user data.
- Update API endpoints to use a configurable base URL for better flexibility.
- Implement enhanced error handling for API responses, including JSON parsing and logging.
- Refactor relay connection logic to utilize a SimplePool for managing multiple relays efficiently.
- Improve user feedback with console logs for connection status and error details.
